Thousands of mourners, from President Barack Obama to ordinary tourists, will pay their final respects to late Supreme Court Justice Antonin Scalia Friday as his casket lies in repose in the high court’s Great Hall.

Court officials said Scalia’s casket would be carried into the hall at approximately 9:30 a.m. local time for a private ceremony including family, friends and justices. The public will be admitted between 10:30 a.m. and 8 p.m.

The justice’s former law clerks will take turns standing vigil by their former boss throughout the day and night in a tradition most recently observed after the 2005 death of former Chief Justice William Rehnquist.
